The SAM is finally removed. The SAM process needs to be developed further before it can be adopted for mass production. Nevertheless, because it can achieve a reduction in the via resistance of about 50% and its TDDB and EM results are equivalent to the process of record (POR), it is likely to be useful in future advanced technologies .

The Table 1 shows that the production of copper by hydrometallurgy with natural bluestone solutions is subject to fluctuation. At the beginning, the mines had a high output, but later, the output decreased with the decreasing bluestone solutions. After a few years, the output decreased significantly, and mines were gradually abandoned.

Silver was discovered after gold and copper about 4000 BC, when it was used in jewelry and as a medium of exchange. The earliest known workings of significant size were those of the pre-Hittites of Cappadocia in eastern Anatolia. Silver is generally found in the combined state in nature, usually in copper or lead mineralization, and by 2000 BC ...

Dressing. The impure lead bulhon, produced from any of the smelting processes, is cooled to remove dissolved copper prior to the refining operation. The operation is referred to as copper drossing, and is performed in one or two 250 t cast-iron ketdes. The process consists of skimming off the dross, stirring the lead, and reskimming.
